Placing Comment-Based Help in Scripts

  • Artigo

This topic explains where to place comment-based help for a script so that the Get-Help cmdlet associates the comment-based help topic with scripts and not with any functions that might be in the script.

Where to Place Comment-Based Help for a Script

  • At the beginning of the script file.

    Script Help can be preceded in the script only by comments and blank lines.

  • At the end of the script file.

    If the first item in the script body (after the Help) is a function declaration, there must be at least two blank lines between the end of the script Help and the function declaration. Otherwise, the Help is interpreted as being Help for the function, not Help for the script.
